First try:

Installing freebsd over my old linux disks (2gig conner and 4 gig seagate).
The fdisk/diaklabeler part of the install process complains that the
geometry on the drives is hosed. So I hit the G key, and let FreeBSD pick
the geometry. It hoses up my drives completely, and I have to do a low
level format before the drives are useful again. The install script aborts
when it tries to make a new fs on the hosed-up drives.

Second try:

Ignored the message this time about bad geometry (after doing a low level
format on the drives). The install completes okay. Upon reboot I get a
message about "there is a drive larger than 1 gig with a 64 head/ 32 sector
partitioning which is not compatable with the 255 head/ 63 sector
translation setting on this card. Data could be corrupted. Hit any key to
.....". After hitting any key, the system comes up okay, but this obviously
is bad, as evidenced by my daily crashes where the computer reboots itself!

Third try:

I turn OFF the option in the Adaptec for "extended BIOS for DOS-drives
larger than 1 gig" figuring maybe that option is ONLY for DOS drives. I
don't get the error messages any more, but it's only been running for a few
hours. Could that be the fix?

Can anyone help me understand what's happening here? Linux never gave me
these problems (using a 1540cf) with the same drives.

Also, what's the recommended process for adding scsi drives (formatting
them, partitioning them and making the new fs's)? The man page for fdisk is
pretty tough to follow, and disklabel's is even worse.

Pointers to FAQs with this info would be great as FreeBSD's site is missing
this part.

Thanks,
Jon
